Q1. Difference between vs Refrigeration
Ans. 
Air conditioning is the process of altering the properties of air to make it more comfortable, while refrigeration is the process of removing heat from a space or substance.
• Air conditioning is used to cool and dehumidify indoor air for comfort.

• Refrigeration is used to preserve food, medicine, and other perishable items.

• Air conditioning uses a refrigerant to absorb heat from indoor air and release it outside.

• Refrigerati...read more

Q1. Define what is hooks law
Ans. 
Hook's law states that the force needed to extend or compress a spring by a certain distance is proportional to that distance.
• Force needed to extend or compress a spring is directly proportional to the displacement

• The formula for Hook's law is F = kx, where F is the force, k is the spring constant, and x is the displacement

• It is used to calculate the behavior of springs, elastic materials, and other systems under stres

Q2. What is pearlite material
Ans. 
Pearlite is a two-phased lamellar structure composed of alternating layers of ferrite and cementite in carbon steel.
• Pearlite forms when austenite transforms during the cooling process of steel

• It is a common microstructure in carbon steels

• Pearlite provides strength and hardness to the steel

• It is often used in engineering applications for its desirable properties

Q1. What is a transformer?
Ans. 
A transformer is an electrical device that transfers electrical energy between circuits through electromagnetic induction.
• Transforms voltage levels: Increases (step-up) or decreases (step-down) voltage.

• Used in power distribution: Essential for transmitting electricity over long distances.

• Consists of primary and secondary coils: Energy is transferred through magnetic fields.

• Example: A step-down transformer reduces 220V
